Lexus GS


Audi A8

Summary

Lexus GS

Ah, yes, the Lexus GS. Toyota's luxury off-shoot had high hopes for the new big boy when I first saw it a few years ago. Not thousands-of-sales high hopes, but the company thought a rear-wheel drive luxury sedan stacked with gear you didn't even know you wanted would be a dead-set winner.

And to be fair, they were right. I ran a GS as a long-termer and it was impeccably-mannered. In hybrid form. It wasn't sparkling, but my goodness, it used barely any fuel; especially impressive given its size.

As the sun is surely setting on the GS, it's time to have a look and see if it's a match for the BMW 5 Series or the Mercedes E.

Audi A8

In a world where genuine wood trim and nappa leather comes in a Mazda6 for under $50,000, premium brands like Audi have been forced to come up with new hallmarks to underpin their status and asking prices.

This is particularly true at the top end of town, with the latest S-Class and 7 Series featuring tech advances that aren't even legally usable at this point.

The new, fourth-generation Audi A8 is no different, packing hardware capable of autonomous driving well ahead of what is currently allowed on any public roads, along with an array of safety, efficiency and convenience firsts for the brand that cement the model's position at the top of the four-ringed luxury tree.

The current S-Class may measure your vital signs and aim to improve your general well-being, but it won't give you a foot massage. If you tick the right options boxes, the new A8 will.

We were among the first to drive the new A8 at its Australian launch around Sydney last week.

Verdict

Lexus GS7.3/10

Weirdly, given all the good things I've had to say about the GS F Sport, it doesn't quite hang together. It's missing that certain something the Europeans have in their chassis, particularly the BMW 5 Series, and with ageing interior tech, it's struggling to keep up.

It's a car built for specific tastes, and they're more California than Straya. And that's perfectly okay, but unfortunately, that doesn't translate to a stampede of buyers. Having said that, none of its German rivals (or its beleaguered Japanese counterpart, Infiniti) could claim wild sales success either.

The GS is a terrific car, underrated but also just not quite there for my taste. The GS F, though, that's another thing altogether.

Does Lexus even register on your big luxury sedan radar? If it does, what stops you from taking the plunge?


Audi A87.9/10

The new A8 is a very accomplished machine, and can certainly be optioned up with enough toys to entertain and comfort whether you're riding in the front or back.

It's not possible to say if its better than the S-Class or 7 Series in isolation, but it has a unique design ambience that's unmistakably Audi. If you're a four-ring devotee, you won't be missing out.

Based on this test, the sweet spot of the range is the long-wheelbase 55 TFSI. At this end of the market, it's fair to say the extra $12,000 for the added length and $3000 for the smoothest and most powerful engine are worth it.

Regardless of the bigger wheels, we'd probably spring for the Premium plus package and the Executive package's rear seat with the Entertainment package for all the most impressive toys. This would mean a total list of almost $250k, but it's arguably how Audi intended the new model to be.

Design

Lexus GS7/10

The GS is ageing well, but it's still a bit heavy-handed around the headlights and a little on the slabby side along the flanks. It doesn't look poised for action, even with the F Sport additions, but nor does it look frumpy, mostly due to the whopping blacked-out spindle grille, a Lexus signature. 

The rear end is good looking but a bit bluff, again neither surprising or delighting.

Little has changed inside, but it's still a very nice cabin, and always will be apart from a couple of clangers (the gear shifter looks super-cheap). 

What's more, it's welcoming, lots of very nice materials, comfortable, seats - it's exactly what it needs to be. Whatever you might think of the looks, one thing is absolutely certain - if anyone builds cars better than Lexus, it's a very, very short list.


Audi A88/10

At first glance the new A8's exterior styling may look a tad obvious, with unmistakably Audi design adding a bunch of straight lines to make things look more serious. 

The reality is far more considered, being the first whole design to emerge under Audi Design boss Marc Lichte's stewardship. Previewed by the first Prologue concept in 2014, the result has an elegance that underlines its position as Audi's flagship and is less likely to be confused with an A6 than the S-Class can be with the E-Class.

If you're after the ultimate in design details and lighting performance, you can also opt for $13,200 laser headlights that can double the range of LED headlights to 600m ahead. This option also brings OLED tail-lights with jewel-like filaments less than 1.0mm thick. 

Compared with the third-generation model it replaces, the size of the new A8 is 37mm longer, 13mm taller but 4.0mm narrower, riding on a 6.0mm longer (2998mm) wheelbase. The long wheelbase version is 130mm longer again in wheelbase and overall. 

It rides on the latest MLBevo architecture shared with the A4, A5, A6, A7, Q5 and Q7, along with the Bentley Bentayga, new Porsche Cayenne and VW Touareg, and the upcoming Q8. 

In A8 guise, it combines aluminium, steel, magnesium and CFRP to result in the biggest material variety used in an Audi to date. Kerb weight ranges from 1995kg for the short-wheelbase petrol model to 2020kg for the long-wheelbase version, with the diesel versions adding 55kg respectively.

A 15-spoke, 19-inch wheel design is standard for Australia, but the Premium plus package fitted to all the cars we tested brings a 10-spoke 20-inch design, while the options list includes another three choices of 20-inch wheels. You can also get 21-inch alloys with the optional Sport package.

As you'll see in the interior images, the A8 represents another significant step forward for Audi design, with horizontal themes and numerous traditional controls now hidden beneath touchpads.

Key among these is the deletion of the centre console controller for the multimedia system, which has been replaced by an 8.6-inch secondary touchscreen beneath the 10.1-inch main screen. Apple CarPlay and Android Auto smartphone interfaces are available via USB connection, and the A8 will act as a mobile Wi-Fi hotspot if you sign up for a data plan.

This split layout is less imposing than using one giant screen as in a Tesla, and both give haptic and acoustic feedback to commands to simplify use while driving. All versions also score the excellent 12.3-inch 'Virtual Cockpit' display ahead of the driver. 

All A8s also now get a smartphone-like back seat remote controller, which enables control of temperature settings, seat adjustment, lighting, media functions and window blinds (when optioned) via its 5.7-inch OLED touchscreen.

Another surprise detail is that the interior door handles are now power assisted, which represents the lengths Audi has gone to in reducing control weights.

Practicality

Lexus GS7/10

Being a big car, there's plenty of room inside. Four passengers will be very comfortable although rear legroom was a bit on the skinny side given the car's size.

The cabin contains a good-sized console bin, four cupholders and each door pocket into which you could conceivably slot a bottle.

The 520-litre boot is a useful shape, with a sensible load height and a space-saver spare under the floor. The 5 Series and E Class both best the Lexus by 10 litres, so the GS isn't far off the norm.


Audi A88/10

Choosing the biggest sedan in the line-up isn't just about outdoing your neighbours, it's also fair to expect enough room to stretch out and ponder your stock options. 

Despite the new A8's minor 6.0mm wheelbase growth, the interior dimensions have grown 32mm in length, which has expanded legroom as well as headroom.

Fundamental practicality elements are covered as well, with a cupholder and bottle holder for each outboard passenger, an array of USB and 12-volt charge points and two ISOFIX child seat mounts for the back seat. There's also a Qi wireless phone charger within the centre console. 

Boot space is a useful 505 litres, and while there's no split-fold for the back seat, there is the capacity to bring curtain rods home from Bunnings via the ski port.  There is also a space saver spare wheel beneath the boot floor. 

Price and features

Lexus GS8/10

We had the pleasure of the GS 350 F Sport for the week, which is well over $10,000 cheaper than the Luxury and is therefore the 'default. If you're not sure what F Sport means, it's Lexus' answer to an M Sport or AMG pack, without all the high-powered engine shenanigans to go with it. If that's what you're after, the V8-powered Lexus GS F is definitely for you.

Starting at $95,300, the F Sport has a spectacular standard features list - 17-speaker stereo, 19-inch alloys, variable-geared four-wheel steer (!), adaptive suspension, dual-zone climate control (with moisturising function), hectares of leather trim, head-up display, electrically-operated heated and ventilated front seats, rear sunshade, F Sport instrument screen, auto LED headlights, keyless entry and start, sat nav, front and rear parking sensors with around-view cameras and a space-saver spare.

The media system is run from Lexus' 12.3-inch screen embedded in the dashboard and controlled from an infuriating console-mounted mouse-clicker with a couple of shortcut buttons. It really is spectacularly irritating and made worse by the rotary dial stationed next to it that acts as the drive mode selector. Why not use that instead? 

As ever, the system is mildly baffling to use and hard to look at, but the sound is absolutely lovely from the Mark Levinson-branded speakers. Lexus is persisting with a DVD player but it also has DAB+.


Audi A87/10

The fact that the new A8's entry price has dropped almost $6000 to $192,000 is likely to have less impact than a $19,990 Hyundai i30 special, but Audi's claim that it offers up to $36,000 more value than before may lower a few bifocals. 

Introducing Audi's new naming scheme, which no longer makes reference to engine capacity in preparation for electrification, the diesel base model wears a 50 TDI badge, before moving $3000 north to the petrol 55 TSFI. Either models can be had in long-wheelbase form (signified by a capital L after A8) which will cost you an additional $15,000 respectively.

The $210,000 A8 L 55 TFSI at the top of the price list is more than $42,000 cheaper than the previous V8 diesel 4.2 TDI and a more than $120,000 less than the previous S8 Plus, but a new performance flagship is due to appear in the near future.

Value is rather subjective at this end of the price scale, but by comparison the entry RRP for the new A8 undercuts the base 7 Series by $34,900, the S-Class by $3900, but starts $1871 above the Lexus LS.

Both the A8's 50 and 55 engines come with the same trim levels, but when the standard kit is this lengthy it's more a matter of features not included in the A8, rather than those that are. 

As you might expect, there's an array of options available. These accessories range from the aforementioned wheel choices and laser lighting to $3600 Alcantara headlining, $4500 all-wheel steering, a $5200 night vision system, or $12,100 3D Bang & Olufsen sound system with 23 speakers. 

There are five options packages also, starting with the $6690 'Entertainment package' which brings a six-disc DVD/CD changer (on top of the standard DVD/CD player) and twin tablets for the rear seats which mount to the front seat headrests. 

The nappa leather trim can be expanded to the upper and lower dash and glovebox, door trims, headrests, centre console, steering wheel airbag cover and the backs of the front seats with the 'Full leather package' for an extra $9950. 

If you can't hold out for the sport edition S8, you can almost look the part with the $9950 'Sport package', which brings a more aggressive front and rear bumper, 21-inch wheels, all-wheel steering and expanded 'piano black' interior trim. 

Audi Australia tells us all A8s ordered to date (along with both cars pictured here) have ticked the $11,000 'Premium plus package', which brings 20-inch rims, adaptive windscreen wipers with integrated jets, chrome exterior details, ambient lighting with variable colours, black control buttons, digital TV, electric rear sunblinds, the full leather package mentioned above, interior fragrancing with ionisation technology, rear tinted windows, softer rear headrests and ventilated massage front seats. 

If you've already selected the rear seat entertainment system, you can also choose the $18,500 'Executive package' which brings individual reclining back seats and extended centre console - which also eliminates the centre rear seat - with folding tables, front and rear seat ventilation and massage function, heated armrests all round and a heated steering wheel. It's the Executive package that also brings the heated rear passenger-side footrest and the foot massage USP.

Engine & trans

Lexus GS8/10

Lexus fits a 3.5-litre (2GR-FKS) naturally-aspirated V6, delivering 232kW/380Nm to help shift the 1745kg GS. Power goes to the rear wheels via an eight-speed automatic. Lexus claims the sprint from 0-100km/h is completed in just six seconds.


Audi A89/10

You might be surprised to learn there's no V8 in the new A8's arsenal - for now, the S8 could change that - but an even greater sign of the times is the return of a petrol version for the first time since 2013. Efficiency gains are the main reason for the petrol comeback, which is explained in detail under the fuel consumption heading below.

Both the 210kW/600Nm 50 TDI turbo-diesel and 250kW/500Nm 55 TFSI petrol specifications use 3.0-litre turbocharged V6s which may seem to be simply plucked from existing models, but they bring mild hybrid technology to the Audi line-up for the first time. 

Unlike conventional hybrids that use an electric motor to provide horsepower to drive the vehicle, a mild hybrid (or MHEV) enables the combustion engine to be switched off when the vehicle is coasting or braking, or effectively as an extension of a start/stop system which conserves fuel when a car is stationary.

The A8's mild hybrid system is facilitated by the move to a 48 volt electrical system, with a supplementary 10Ah lithium-ion battery mounted in the boot to keep the electrical systems fed for up to 40 seconds with the engine switched off. Audi claims the system has the capacity to save up to 0.7L/100km.

An extra starter motor has been integrated with the alternator to restart the engine more smoothly via a belt, rather than the conventional cog and ring gear used by the dedicated starter motor for cold starts.

Both engine specs deliver their max torque rating from just above idle, with the 50 TDI at 1250rpm and the 55 TSFI at 1370. Claimed 0-100km/h acceleration performance figures are an impressive 5.9s and 5.6s respectively.

Like all recent longitudinal-engined Audis, the new A8 uses a version of ZF's much lauded eight-speed torque converter auto gearbox, and both engines send power to all four wheels via the 'quattro' all-wheel drive system. 

The optional all-wheel steer system can twist the rear wheels by as much as five degrees, reducing the turning circle by around 1.0m at slow speeds. While at higher speeds, the rear wheels move parallel with the fronts by as much as two degrees to improve stability, particularly for rapid lane changes and evasive manoeuvres. 

All new A8 variants carry a maximum braked towing capacity of 2300kg.

Fuel consumption

Lexus GS6/10

A real world 13.7L/100km is a solid miss of the claimed 9.3L/100km, which itself is hardly earth-shattering. It's a big heavy car and that's the penalty. It drinks fuel fast, so the 66-litre fuel tank does drain quickly and it's worth knowing you have to fill it with the 95 RON or better.


Audi A88/10

Gone are the days where full-size luxury sedans got away with devil-may-care fuel consumption, and even though they still spin six cylinders and need to move around two tonnes, the 55 TFSI petrol versions manage an 8.2L/100km official combined figure. This is when using at least 95 RON Premium unleaded of course. 

As you'd expect, the diesel fuel economy is even better with 5.9-6.0 official figures across wheelbases.

With a fuel tank capacity of 72 litres, this suggests a theoretical range between fills of 878km for the petrol models, and between 1200-1220km for the diesels. The A8's spec sheet lists the option of an 82-litre tank if they aren't quite far enough for you.

Driving

Lexus GS7/10

There are things you expect in a Lexus. Quietness. Composure. Smoothness. The GS delivers all three of those things effortlessly. But it has a few extra things in its bag that I can't say I was expecting.

For a start, the 3.5-litre V6 moves the car without any carry-on and in doing so, I was constantly amazed at how quickly the speed in the head-up display reached the posted limit. It just doesn't feel or sound like a six second car, but there you are. The transmission is virtually faultless, the engine sound distant and refined, the power impressive.

It's a heavy car, no question, but two things work to make it feel much lighter. First - and it doesn't matter which mode you choose - the adaptive suspension somehow knocks about 200kg out of how heavy the car feels. The brakes, while a little soft on pedal feel when you first step on them, are very effective and again help to make the car feel lighter than it is.

The four driving modes are quite distinct. As usual, Eco makes everything soft and doughy or as I prefer to say, unpleasant. Normal is great for every day, with just the right throttle response and steering weight.

Moving to sport ups the aggro slightly while Sport+, while never harsh, firms everything up to the point where it starts to feel like a different car. Sport+ makes the car feel race-car pointy, the suspension holds the body in check and the power seems readily available without jerky progression

The all-wheel steer is a big part of the change in feel. It's is especially sharp in Sport+ mode. The steering's gearing changes up quite a bit, meaning a lot less steering lock required for your favourite hairpin bend. Of course, at real speed it all calms down because neither you nor Lexus are fond of sneezy lane-changes or Armco-swiping. At first I thought it just made the big car feel a bit too nervous but as I got used to it (and was able to dial it down by switching back into a less racy mode) I found it fun but a little bit out of character with the car itself.

And just because it's the F Sport, that doesn't mean it can't do all the things you'd expect from a Lexus. You can still waft, you can still creep up on people and it's really very comfortable when you're cruising or stuck in traffic. 


Audi A88/10

Our test started in the worst of Sydney morning traffic, which presented the chance to put the latest adaptive cruise assist (ACA) system through its paces on a very clogged Eastern Distributor. 

I'm a huge fan of active cruise control systems that guide the vehicle from speed to a stop, but the A8's ability to start moving again is another step beyond. It helps you avoid being ‘that guy' who hasn't noticed the traffic moving, and would no doubt work wonders for traffic flow if all cars were so equipped. Given the chance, Audi says this system works all the way from 0-250km/h.  

No matter what your reaction to the A8's exterior, the freshness of the interior design is like no other, and everything you touch feels first class. 

The four-spoke steering wheel has a surprisingly large diameter and is shared with the upcoming A6, but uses thinner spokes than the norm to promote visibility of the virtual cockpit display as the wheel is twirled.

The haptic and acoustic screens make it as easy as we've experienced to handle a touchscreen while driving, but not quite as simple as the previous console controller. 

Front and rear seats are softly padded for comfort rather than support, and unsurprisingly there's ample room in every direction for this 172cm tester, regardless of wheelbase.

All examples of the A8 we drove were optioned with the Premium plus package, which means one inch larger 20-inch alloys. Despite all A8s coming standard with adaptive air suspension, small bumps like cats eyes and expansion joints are more noticeable than you might expect. As is often the case, the standard 19-inch alloy wheels are likely to be the solution.

We drove both engines and wheelbase choices at the A8 launch event, and you need to be paying close attention to hear any extra noise from the diesel. It does make a muted groan under throttle, but likely worth the 300-plus kilometres of extra range if that's what you're after. 

The diesel's smoothness is also no doubt aided by its use of active engine mounts. If you're after outright refinement and performance, the petrol is the one for you but neither feel in any way sluggish. 

Heading through the bends of the Royal National Park and then back over the hills via Macquarie Pass at pace, there was no disguising the fact that the A8 is a big car, and it tends to float unless you select 'Dynamic' from the drive mode selector. Regardless of mode, it's more planted than any luxury SUV.  

Making a bee-line back to Sydney via the Hume, the A8 simply wafted along at 110km/h in near silence. As you'd expect.

Safety

Lexus GS7/10

The GS scores 10 airbags, ABS, stability and traction controls, blind spot monitoring, rear cross traffic alert, forward AEB, active cruise, auto high beams and lane departure warning with lane keep assist.

The GS doesn't have an ANCAP or Euro NCAP rating while the USA's IIHS (Insurance Institute for Highway Safety) rating is good for each key crash-worthiness measure. The IIHS suite of tests is quite rigorous but differ from our ANCAP/Euro NCAP standards.


Audi A88/10

The new A8 is yet to score a rating from ANCAP or Euro NCAP, but comes with a brand-leading array of safety features. 

All versions come with all the airbags, alerts, self parking, lane assist, self driving, front and rear AEB, 360 degree and reversing cameras, parking sensors and traction aids you'd expect. 

The airbag count has been further bolstered by an industry-first centre airbag, which has been designed to prevent head clashes between front seat occupants. This also represents Audi thinking beyond any Euro NCAP or ANCAP criteria.

It also comes with Audi's exit warning system, which warns the driver of passing cars or cyclists but can now delay the door opening in case the driver doesn't see the warning light. 

A front-mounted laser scanner replaces the usual radar system for active cruise control and front AEB, which doubles the range of a radar scanner to 80m and enables both functions to work at speeds up to 250km/h.

This laser scanner is also key to the A8's Level 3 autonomous preparation, but local laws limit its capability to active cruise control with lane assist.

Ownership

Lexus GS8/10

There's one area where Lexus smashes the Germans and that's after-sales. While the warranty is hardly ground-breaking at four years/100,000km and service intervals are reasonable at 12 months/15,000km, it's how it all comes together.

For the duration of the warranty, when the car needs a service, Lexus will either come and get it then return it to you, or give you a loan car. Anecdotal evidence suggests this continues long after the warranty runs out. Like, 10 years after the warranty runs out. 

This is a small thing, but if there's one thing I hate about car ownership, it's the servicing experience. If I was a betting man, I'd dare you to find someone who genuinely has a problem with Lexus after-sales care.

On top of that, you get a generous roadside assist package for four years. 


Audi A87/10

Like all Audis, the new A8 is covered by a three year, unlimited kilometre warranty. This is short of the five year-plus periods becoming more common among mainstream brands, but equal to the terms offered by BMW and Mercedes-Benz. Lexus differs by offering a four year, 100,000km plan.

Service intervals and capped price servicing mirror the previous A8, with a 12 month/15,000km schedule, and maintenance costs for the first three services can be wrapped into a package for $1900. 

We had no issues during our test, but any common faults, common problems or reliability issues are likely to appear on our A8 problems page.
